Title: Ratio adapter
Post by: Gusgus74 on December 14, 2010, 12:15:15 am

My 74 c10 has a ratio adapter attached to the speedo cable at the trans tailshaft. Did these trucks come with these adapters from the factory or did the PO install it? I need to correct the speedo which now reads about 10 MPH slower than actual.
